All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
The embodiment provides a construction precision control method for container ship hatches in an integrated mode, and aims to manufacture a torsion box and hatch coaming total assembly and guarantee the precision of the total assembly. The method specifically comprises the following steps:
s1, independently manufacturing a hatch coaming segment 5, a main plate segment 1, an outer plate segment 2, an inner deck segment 3 and an outer deck segment 4 on a jig, wherein the manufacturing of the hatch coaming segment 5, the main plate segment 1, the outer plate segment 2, the inner deck segment 3 and the outer deck segment 4 comprises the following steps:
s1.1, cutting a thick plate 6: the thick plate 6 is made of steel material, the thickness is more than or equal to 35mm and can reach 68mm to the maximum, flame cutting is adopted, and the precision requirement of the cut thick plate 6 is as follows: the deviation of the length and the width is less than 2mm, the deviation of the diagonal is less than 3mm, and the straightness is within 2mm/10 m; because the heat output of flame cutting is large, the diagonal distortion and poor straightness can be caused, and therefore, in the flame cutting process, the straightness of the cutting machine track, the perpendicularity of the cutting nozzle and the cutting speed need to be strictly controlled to ensure that the diagonal deviation and the straightness of the thick plate 6 meet the requirements.
S1.2, splicing a thick plate 6; after the thick plate 6 is assembled according to the requirements of the drawing, preheating the thick plate 6 to ensure that the temperature of the thick plate 6 is more than or equal to 120 ℃.
S1.3, welding a thick plate 6; firstly, performing tack welding, wherein the length of a tack weld is more than or equal to 50mm, the distance between adjacent tack welds is 200mm, and the height of a welding leg is 3-5mm, after the tack welding is finished, welding a first surface of a thick plate 6, after the welding of the first surface is finished, turning over, performing carbon planing on the tack weld, and then performing cover surface welding; the welding collapse phenomenon can be caused in the welding process due to the pre-thermal deformation in the previous step, and the problem can be solved by increasing the length of the positioning welding line in the step.
And S2, assembling and welding the main plate segment 1, the outer plate segment 2, the inner deck segment 3 and the outer deck segment 4 for the first time, wherein the main plate segment 1, the outer plate segment 2, the inner deck segment 3 and the outer deck segment 4 are assembled to form a rectangular torsion box.
S3, marking a hatch coaming installation line on the outer deck segment 4, assembling and welding the inner longitudinal wall of the hatch coaming segment 5 and the outer deck segment 4 for the first time, welding the front full weld for the first time, reinforcing and fixing the hatch coaming segment 5 and the outer deck segment 4 by adopting channel steel in the welding process, reinforcing and fixing the channel steel, avoiding the spatial displacement of the hatch coaming segment 5 caused by welding shrinkage, and ensuring that the relative size of the hatch coaming segment 5 and the torsion box is unchanged in spatial positioning. And after the assembly is finished, measuring the installation precision through a total station.
And S4, turning the total assembly to finish secondary welding of the main plate segment 1, the outer plate segment 2, the inner deck segment 3 and the outer deck segment 4 and secondary welding of the hatch coaming segment 5 and the outer deck segment 4.
In the step S1.3, the end of the thick plate 6 adopts a V-shaped groove, and an X-shaped weld is formed between the thick plate 6 and the thick plate 6.
Because the width of the surface of the welding seam is large and the filling amount is large in the welding process, the end of the thick plate 6 is easy to warp in the welding process, and therefore the thick plate 6 is provided with a reverse deformation allowance before the tack welding, specifically: the position of the thick plate 6 with smaller thickness in the two thick plates 6, which is 2.5m away from the welding seam, is reduced by 10mm, one thick plate with larger thickness in the two thick plates 6 is kept horizontal and is compacted and fixed by a weight on the side far away from the welding seam, and if the two thick plates are the same in thickness, any one thick plate is selected as the thick plate with smaller thickness; the method comprises the following steps of (1) setting reversible deformation allowance after carbon planing and before cover surface welding of a welding seam, specifically: the height of the thick plate 6 with smaller thickness from the welding seam is adjusted to be lower by the same value as the depth of the carbon plane at the position 1.5m away from the welding seam, and one thick plate 6 with larger thickness is kept horizontal and is compacted and fixed by a weight at the side far away from the welding seam.
The specific process of step S2 is as follows: the method comprises the steps of placing a main board segment 1 on a horizontal jig, hoisting an inner deck segment 3 and an outer deck segment 4 on two sides of the main board segment 1, fully welding the front sides of the main board segment 1, enabling the inner deck segment 3 and the outer deck segment 4 to be perpendicular to the main board segment 1, hoisting an outer board segment 2 on the tops of the inner deck segment 3 and the outer deck segment 4 after welding is completed, and carrying out spot welding on seams of the outer board segment 2 and the inner deck segment 3 and the outer deck segment 4 respectively. The main plate segment 1, the outer plate segment 2, the inner deck segment 3 and the outer deck segment 4 need to be preheated respectively before assembly and welding, and the temperature after preheating is more than or equal to 120 ℃. The two ends of the main board segment 1 are V-shaped grooves, welding seams formed by the main board segment 1, the inner deck segment 3 and the outer deck segment 4 are K-shaped welding seams, and deep fusion welding is adopted for welding; the top ends of the inner deck section 3 and the outer deck section 4 are V-shaped grooves, welding seams formed by the inner deck section 3, the outer deck section 4 and the outer plate section 2 are K-shaped welding seams, and deep fusion welding is adopted for welding.
In step S3, before the hatch coaming section 5 and the inner deck section 3 are assembled, the inner longitudinal wall of the hatch coaming section 5 needs to be subjected to fire correction, the straight line pair of the inner longitudinal wall of the hatch coaming section 5 is detected, and the straightness of the inner longitudinal wall of the hatch coaming section 5 is adjusted to be within 3mm/15 m. Before welding the inner longitudinal wall of the hatch coaming segment 5 and the outer deck segment 4, a reversible deformation allowance is set, specifically, the position of the inner longitudinal wall of the hatch coaming segment 5, which is 1.7m away from the welding line, is adjusted to be 5mm lower, in this embodiment, the width of the hatch coaming segment 5 is 1.7 m.
In step S4, before the assembly is turned over, all the internal components of the torsion box must be welded to avoid the turning over and twisting, and cross-bracing is welded inside the torsion box to prevent the twisting phenomenon caused by welding and turning over, which would result in a large cutting correction during the butt joint of the assembly. Because the whole thick plates are arranged at the position, the cutting length is not enough, the connection cannot be carried out, the cutting length is large, a lot of manpower and material resources are wasted, and the dock period is occupied. Welding a shape-preserving clapboard at the fillet weld positions of the main plate segment 1 and the inner deck segment 3, the fillet weld positions of the main plate segment 1 and the outer deck segment 4, the fillet weld positions of the outer plate segment 2 and the inner deck segment 3 and the fillet weld positions of the main plate segment 1 and the inner deck segment 3, wherein the shape-preserving clapboard is parallel to the cross section of the anti-torsion box, so that the angle of the position is prevented from being distorted due to welding shrinkage stress, the fillet welds are deep fusion welds, the number of welding layers is as many as 30, the distortion of the anti-torsion box is easily caused due to large welding quantity, and the straightness of the inner longitudinal wall of the hatch coaming segment 5. After the assembly is turned over, the main plate segment 1 and the inner deck segment 3, and the main plate segment 1 and the outer deck segment 4 are subjected to back full-weld welding, the inner longitudinal wall of the hatch coaming segment 5 and the outer deck segment 4 are subjected to back full-weld welding, and the outer plate segment 2 and the inner deck segment 3, and the outer plate segment 2 and the outer deck segment 4 are subjected to full-weld welding.
Although the present invention has been described in detail with respect to the above embodiments, it will be understood by those skilled in the art that modifications or improvements based on the disclosure of the present invention may be made without departing from the spirit and scope of the invention, and these modifications and improvements are within the spirit and scope of the invention.
